So, wait.  You're saying that it *works for a little while* after
you log in, and then at some point later, it *stops working*?

If that's actually the case, then maybe you can pinpoint the offending
X resource by doing

xrdb -query > working

right after you log in (possibly after verifying that emacs is in fact
working properly).

Then, after it stops working properly, run the xrdb -query command
again, but redirect it to a different file.  Then use diff to see
what changed.
